AeroTech RMS K750ST-PS Rocket Motor Reload Kit New Product Information Release 7/11/22

AeroTech/Quest is pleased to announce the Tripoli certification and immediate availability of our new RMS Reloadable Motor System K750ST-PS rocket motor reload kit, AeroTech’s 2nd rocket motor reload kit designed to use the single-grain RMS-75/1280 hardware.

Perfect for heavy rockets launched from small fields, the K750ST-PS delivers 1,298.7 N-Sec (292.0 lb.- Sec.) of total impulse with a 1.74 burn time and an all-up weight in motor hardware of 4.29 lb. (1,945.9 g). It’s also a great booster for two-stage rockets, and features AeroTech’s aerospace-grade Super Thunder (ST) propellant formulation with a burn rate midway between Blue Thunder and Warp-9 propellant types. The K750ST-PS generates a peak thrust of 835.7 N (187.9 lb.) with an average thrust of 746.6 N (167.9 lb.).

SMT Designs releases all of their rocketry designs to public domain

Steve Thatcher: "With my upcoming LDRS 40 trip and TRA Tech session there on "3D Printed Modular Avionics Bays", I wanted to make an announcement, so here it is..."

Steve Thatcher says “I am in the process of releasing all of my rocketry designs to the public domain under Creative Commons Attribution-ShareAlike 4.0 International”

You can read the licensing in detail at https://creativecommons.org/licenses/by-sa/4.0/

You can find the designs on http://www.tinkercad.com/ by simply doing a "People" search for "SteveThatcher".  

Once you find the profile, click it to view the parts.

Steve has also tagged the parts with “SMTDESIGNS”, “AVBAY”, and “ROCKETRY”, but you will get more "hits" that way of other non-related parts.

My intent in doing this is to propagate the footprint standard I created for devices and batteries over the last years, so the rocketry community could benefit.

Thatcher says “I would also like to see my designs come to a greater use by making them available for no cost to those that have the required equipment.”

Steve asks that the footprints for carriers and platforms remain unchanged.  Thatcher says”I recognize the need to change things when necessary, but changing footprints negates the universal benefit they provide.  Take the time to look at my entire library of parts to get a system view of why things were done.”

Steve will be available to answer questions through SMT Designs, and the SMT Designs facebook page. _______________________________

Tripoli News

During the LDRS 40 Member's Banquet it was announced that that the Tripoli Wisconsin Association, Tripoli Green Bay, and Tripoli Chicago will be hosting LDRS 41 at the Richard Bong Recreation Area located in Kenosha County, Wisconsin.

The event is planned to take place July 6, 7, 8 and 9, 2023.  

More details and information will be coming soon.

New Unified TRA Safety Code   https://www.tripoli.org/content.aspx?page_id=22&club_id=795696&module_id=520420

Tripoli Rocketry Association unveiled its new “unified” safety code on May1 of this year.

President Bob Brown notes that: Under this safety code, there are no longer Commercial launches or Research launches, just Tripoli launches.  There are some changes to the current safety code, such as a common safe distance table, a safety code for both model rockets as well as radio-controlled boosted gliders as well as other changes.   Tripoli asks all members to please take the time to read the document in its entirety.  

Mr. Brown notes that “While your first reaction will probably be there seem to be a lot more rules under this new document, in fact, almost nothing more restrictive has been adopted it’s just compiled into one document now.”

TRA notes that they owe a huge thank you to Steve Shannon, “who undertook the daunting task of compiling the information from the original four documents and writing (in plain English, not legalese) a document we can all understand and follow”. ____________________________________

2022 NASA Student Launch results   Each year, NASA challenges middle school, high school, college, and university students from across the United States to design, build and launch a high-powered amateur rocket, fly it to an altitude between 4,000 and 6,000 feet, and make a successful landing.

Middle and high school teams could choose to attempt the college/university division challenge or develop their own science or engineering experiment.

Teams in the college/university division tackled a new task that mirrors NASA’s missions like the Mars Curiosity Rover.  Teams had to design a payload capable of autonomously locating where their rocket landed by identifying the rocket’s grid position on an aerial image of the launch site while transmitting the data back to their ground station. 

This had to be accomplished without the use of GPS. The requirement simulates a challenge faced by NASA’s mission managers – communicating with spacecraft and payloads on distant plan mmmm etary bodies, where use of GPS is not an option.   Sixty teams from 22 states including Puerto Rico took part in this year’s competition, with 27 teams launching April 23 near NASA’s Marshall Space Flight Center in Huntsville, Alabama. Teams that did not travel were allowed to conduct their final test flights at a home launch field.

For the second year in a row, The University of North Carolina at Charlotte won the launch division, while Tarleton State University in Stephenville, Texas, won first place in the design division of NASA’s 2022 Student Launch rocketry competition.

The University of North Carolina at Charlotte will receive $5,000 for first place in the launch division, and Tarleton State University will receive $2,500 for first place in the design division.

The top five teams in the launch division are:

University of North Carolina at Charlotte University of Notre Dame, Notre Dame, Indiana Vanderbilt University, Nashville, Tennessee University of Florida, Gainesville Purdue University, West Lafayette, Indiana The top two teams in the design division are: Tarleton State University, Stephenville, Texas New York University   ______________________________________   American Rocketry Contest (TARC)  https://rocketcontest.org/result/2022/   1) Newport High School - Team 2 from Bellevue, WA  (22-1326)   $20,000  (Flight 1)  2  (Flight 2) 11 Total Score = 13 2) Newport High School - Team 1 from Bellevue, WA (22-1804)   $15,000  (Flight 1) 2 (Flight 2) 12 Total Score 14 3) All Saints Episcopal School from Haslet, TX (22-1126) $12,500  (Flight 1) 6.12 (Flight 2) 11 Total Score = 17.12 4) Spring Grove Area Intermediate School - Team 2 from Spring Grove, PA (22-1534)  $10,000  (Flight 1) 13 (Flight 2) 6.8 Total Score = 19.8 5) Coleman High School from Coleman, TX (22-1645)  $7,500  (Flight 1) 10.12 (Flight 2) 10  Total Score = 20.12 6) Creekview High School - Team 3, from Canton, GA $3,500  (Flight 1) 17.2 (Flight 2) 7 Total Score = 24.2  7) Camas High School from Camas, WA (22-1495)  $2.500  (Flight 1) 9, (Flight 2) 16.16 Total Score = 25.16 8) Young Engineers in Action from Hawaiian Gardens, CA (22-1500) $2,500  (Flight 1) 19.64, (Flight 2) 10, Total Score = 29.64 9) Thomas Jefferson High School - Team 9 from Alexandria, VA (22-1764) $2,500  (Flight 1) 7 (Flight 2) 26.8, Total Score = 33.8 10)  Tharptown High School from Russellville, AL  (Flight 1) 1 (Flight 2) 34.12, Total Score = 35.12   Each school or organization for teams 1-5 also receives $1,000.

#13 Mike Nowak and James Duffy – FAI Competition Rocketry

The Model Rocket Show https://themodelrocketshow.com/13-2/

James Duffy, left, and Mike Nowak, right, at the opening ceremonies of the European Space Modeling Competition in Ukraine, 2015

Here’s an episode we recorded a while back, and since it’s been a hot topic recently due to virtual NARCON, we’re dropping it now.

We chat with Mike Nowak and James Duffy – two skilled rocket builders who’ve been competing on the American team in international rocketry competitions for years. FAI – the Fédération Aéronautique Internationale – is the world governing body for air sports, including model rocketry. The International Championships for Spacemodeling are frequently held in Europe, and until next year, have never been held in the United States.

That’s about to change, as the Internats will be held in the U.S. in 2023, giving Americans the opportunity to fly for the national team without the often challenging aspects of getting themselves – and their fragile model rockets – overseas.

We talk with Mike and James about what it takes to build good competition scale models, what competing in the internationals is like, and much more, on this episode of The Model Rocket Show.

In other news, the N00b has opened an Etsy shop of rocketry-related t-shirts and coffee mugs. You can find it by clicking here.
